CHARLES .DE TALL-TONI), OF NEW] YORK, N. Y.

LINK.

Application filed February 7, 1923.

T 0 oil whom it may concern.

Be it knownthat 1, CHARLES DE TALMoNo, a citizen ofthe United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Links, of which thefollowing is a specification.

This invention relates to links and more particularly to a novel andimproved sectional link which is adapted to be separated by lateralpressure and avoiding the objec tion of causing the said links to bedisconnected when a pull is exerted on the cuff for instance of a shirt.

The primary object of my invention is the provision of a pair ofcomplementary annular heads or buttons including provision whereby saidmembers may be connected together by sliding one member across the otheras distinguished from those constructions wherein the respective buttonsare pressed together and toward each other, now in common use.

One of the objects of my invention is the provision of a link whereinone member is provided with a gripping means and. the second member witha tongue insertable between said gripping means including positiveprovision for preventing the separation of the respective members fromeach other by a pull or strain.

1 accomplish the above objects and others which will be more readilyunderstood when taken in connection with the accompanying drawings,showing a preferred embodiment of my invention and wherein,

Figure 1 is a side view partly in section showing the cooperatingbuttons.

Figure 2 is a sectional view showing the cooperating members in theirlocked position.

Figure 3 is a similar view and showing the tongue inserted from theopposite side.

Figure 4 is a perspective View showing the buttons disconnected.

*igure 5 is a bottom plan of one of the buttons, and

Figure 6 is a bottom plan of the complementary button.

Referring now to the drawings wherein like reference charactersdesignate corresponding parts throughout the several views, the buttonis formed of two parts wherein the heads 5, 6, are preferably integralwith Serial No. 617,597.

the shank 7, 8, said heads being made to present an ornamentalappearance, if desired, in the manner well understood. The shank 7 isprovided with an annular disk 9 of a diameter slightly smaller than thediameter of the head 5 and connected to said disk, I have provided asubstantially L- shaped tongue 10, which tapers toward its center 11 andterminates in a triangular end 12 as clearly shown by Figure2 of thedrawing and for a purpose presently to appear.

The shank 8 is also provided with an annular plate 13 substantiallyofthe same diameter as the plate 9, said plate 13 being provided withsegmental opposed slots 14, 15, to permit the passage of the tongue fromeither side. The plate 13 is somewhat thicker than the disk 9, so as toreceive a pair of looped springs 16, 17, the respective ends of thesprings being cemented orsecured as indicated at 18, adjacent theopening 15. It will be noted that the outer side of the springs 16,.17,are shaped to con form with the plate 13 and the free ends 19 of saidsprings are curved so as to be disposed toward each other andsubstantially in a central position within the body of the plate 13above referred to. The extreme free ends 20 of the springs are bowedslightly outwardly so as to permit the passage of the tongue 10 when thesame is inserted through the recess or slot 15. In addition it will alsobe observed that the tongue 10 is slightly curved throughout its lengthso as to provide a frictional grip when the respective sections areconnected as above indicated.

By reason of this construction the respective sections of the button asa unit, are capable of attachment, that is to say, either section may bemoved laterally with respect to the other from either side when it isdesired to lock the same and in the same manner, a slight lateralpressure, by the fingers,

of one section will release the same from the other, for the purposewell understood.

While T have illustrated and described my invention with some degree ofparticularity, I realize that in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing theform of the details of construction or other wise altering thearrangement of the cor- "I claim as new and desire to secure by UnitedStates Letters Patent is:- 1. A fastener comprising tWo complej mentarymembers each member having an outer face and a shank, a tongue extendlngacross the shank of one of the members and means carried by the secondmember for receiving andlocking the tongue from either side. I

2. A fastener comprising two complementary members, each member havingan outer face and a shank, a tongue formed on one of the members anddisposed atright angles to its shank, the second member havingopposedslots for receiving the tongue and resilientgripping means for engagingthe tongue when the latter is inserted through either of the slots.

3. A fastener comprising tWo complementary members, each member havingan outer face and a shank, a curved tongue formed on one of said membersand disposed at right angles to the shank and face, a disk havingopposed slots in the second member and opposed gripping elements carriedby the disk to engage and lock the said tongue when inserted througheither of the said slots.

4. A fastener comprising two complecmentary members, each member havingan outer face and a shank, a plate having a tongue formed therewith onthe shank of one of the members, a disk carried by the shank of thesecond member, said disk havthe latter is inserted through either of theslots. .c

5.'A fastener comprising two com-plementary members, each .member havingan outer face and a shank, a plate having" a slightly curved tongueformed .ther ew ith extending across the'slhank of one of the members,said tongue having atapered end, a disk carried by the shank of thesecond member, said disk having opposed, segmental slots to permit thepassage of the tongue, resilient, curved springs secured Within the saiddisk and lying icontiguous the periphery thereof to engage and grip thesides of the tongue When the latter is inserted through either of theslots.
